Re: Attaching small trim pieces?

Are the old ones on your car totally gone? You might see if any of the vendors have any of the #437158 retainers called for. If not, then you will have to measure the diameter of the stud. The length is usually not as important but might as well have it if you wind up having to get a closed end speednut. Once you know what stud size to order, then just a matter of drilling the proper sized outside hole.

Speednuts come in different styles and sizes. The clip Packard calls for seems quite large in diameter if they are asking for a .385 to .390 hole but I don't know the stud size or what it looks like. Maybe packardguy53 could post a picture if he hasn't installed them already.


Here are a couple of basic clip--again, many styles. In the first one, you push it into the drilled hole & barbs on the outside compress when inserting in the hole and spring back. Tangs on the inside grab the stud. In the second, the whole sleeve compresses slightly to slip in then expands back out and locks in the hole at the narrow opening just below the flange. Once the retainer is locked in, the trim piece is pushed in and the tangs on the inside grab onto the stud. Once the stud is in, the whole assembly is locked in and can't move.
